Development and validation of a coupled numerical model for offshore floating multi-purpose platforms

A Multi-Purpose Platform (MPP) is an offshore system designed to serve the purposes of more than one offshore industry. Over the past decades, a number of industries have expanded or are expanding, from onshore to offshore locations. In the present work, the MPP proposed in the framework of Blue Growth Farm project is considered. The aim here is to develop and validate a coupled aero-hydro-servo-elastic numerical model, which will be used to predict the dynamic response of the MPP under a wide range of environmental conditions. Model test research was conducted to validate the developed numerical model. The model test was carried out in the water basin at Centrale Nantes, employing the Froude scale strategy. An innovative approach to modelling wind load in the experimental environment was proposed and applied. This paper reports the up-to-date research outcome of the Blue Growth Farm project - numerical model development and validation.
